Although the high-pressure hydrogen storage tank can be matched with the hydrogen-burning power generation, heating and hydrogen fuel cells, the use of the high-pressure hydrogen storage tank is at great risk, so that the high-pressure hydrogen storage tank is difficult to apply to the civil market on a large scale.

Working principle:
firstly, taking a solid magnesium-based hydrogen storage material as an example, when the magnesium-based hydrogen storage material is charged and discharged with hydrogen, the reaction equation is as follows:
i.e. exothermic reaction during charging and endothermic reaction during discharging, the ideal reaction temperature is 350 ℃.
When discharging hydrogen, the heating controller 13 is started to control and heat the electric heating pipe 12, in the embodiment, the electric heating pipe 12 adopts a radiation type electric heating pipe, the electric heating pipe 12 is used for heating the hydrogen storage material in the hydrogen storage metal tank 7, when the hydrogen storage container is heated to 200 ℃, a small amount of hydrogen is discharged, along with the temperature rise, the hydrogen discharge speed is continuously increased until the maximum hydrogen discharge speed is reached at 380 ℃, and at the moment, the hydrogen output can be controlled by adjusting the heating power of the electric heating pipe 12 according to the hydrogen consumption requirement. The hydrogen generated by the hydrogen storage metal tank 7 is cooled to below 80 ℃ by the cooler 20 on the first pipeline 8, then passes through the first pressure sensor 21 to the first electromagnetic valve 14, and when the pressure monitored by the first pressure sensor 21 exceeds 1.3MPa, the first electromagnetic valve 14 and the second electromagnetic valve 15 are opened for hydrogen output. When the operation is stopped, the electric heating pipe 12, the first electromagnetic valve 14 and the second electromagnetic valve 15 are closed, and the system can be completely closed. If the value of the first pressure sensor 21 cannot exceed.3 MPa at start-up or operation, it can be considered that the hydrogen in the multi-tube hydrogen storage vessel has been exhausted and needs to be charged.

When the values of the first temperature sensor 17 and the second temperature sensor 18 are close and the value of the temperature sensor 22 is less than 250 ℃, the charging is considered to be finished, the first electromagnetic valve 14 and the third electromagnetic valve 16 are closed, and the charging is stopped.
